Instruction manual – MU-C/S 5

2. Important operating and safety instructions

This part of the manual is not long. Please read it right through.

Your new Müthing mulcher was expensive. But your life and personal safety are even more
valuable. So always pay proper attention to your own safety and that of other people.

This not

only applies to operating the machine but also to care and maintenance. You will find detailed

instructions on safety and risks from page 16 onwards.

In order to avoid risks, work safely and maintain the value of your new Müthing mulcher for many
years to come please pay attention to all the instructions given you by our dealer and always think
before you act. Read the complete manual and familiarise yourself with the machine, its proper use,
possible risks and safe handling. It should only be operated by competent people.

1) Permissible power range. It is essential to adhere to the performance specifications for your
mulcher type and not to exceed the maximum vehicle/tractor KW ( HP ).

The manual covers
mulcher types MU-C/S for tractor performance from 10-18 KW (15-25 HP). Only one type is
correct – you will find the precise details for your mulcher in the technical data inside your
spares list on page 6.

2) Mounting. As soon as you have hitched your mulcher to the tractor, remove the locking bolts from the

support legs, raise the legs and re-secure them with the locking bolts.

Then gently raise the lower

links (control device floating freely) so that the headstock is precisely vertical and straight

.

Readjust with the upper link if necessary.
If the mulcher is inclined too far forward it will cut too low and may clog and dig in. Having the
mulcher inclined backwards will place too much strain on the support roller. In both cases
there is a risk of debris such as stones etc flying out to the front or the rear when working. If
the lower link and the upper link are set correctly as described, the glide shoes on the mulcher
housing will be parallel with the ground.

3) P.T.O. shafts that are distorted beyond a certain extent lose their film of lubricant, run hot and

the universal joints fly apart. Look out for distortion and grease regularly!

Ensure that distortion

at the front of the P.T.O. joint more or less matches that at the rear (uniform Z-diffraction
required).

4) The height of the mulcher is set via the back-up roller (basic setting by means of the three

holes) and the upper link (fine adjustment). On the roller you should generally use the central
hole on the side plate. Don't cut too short! Give the grass a chance to sprout up again
In unfamiliar areas such as fallow ground and field edges it is a good idea to use the lower
hole, i.e. cut higher

. There is no way of telling what debris and rootstalks are lurking there.

If possible, steering device of 45 – 90° cylinder at floating position!

The machine should adjust

to the ground of its own accord. This takes pressure away from pivots and cylinders.

5) Driving. If the mulcher is taken round sharp bends on the back-up roller even the best

bearings in the world cannot stand this indefinitely. Lift it off or raise the mulcher on bends and
when turning.

6) Speed. The slower the better! The longer the chaff remains in the housing, the more it is cut

and crushed, meaning that it will rot better and more quickly. – Driving slowly at the edges of
fields, roads and tracks also makes it easier to stop in time to avoid obstacles.
Side marchers develop very considerable leverage. so that the left side of the tractor (or, with
left-hand models, the right side of the tractor) can encounter a substantial reduction in load,
especially when taking bends. Drive with consideration!

7) Quality of cut. Keep as close as possible to the stated P.T.O. speed – never exceed it! If the

rotor can operate at the rated speed, suction is intense and crushing is good. If the engine
speed is too high the rotor, bearings and the power train could be damaged

6 Instruction manual – MU-C/S

With mulching you can almost always wait until it is dry and the ground is in reasonable
condition. It doesn’t have to be done on one particular day.

8) Length of cut. The shorter the better and the quicker it will rot. The length of cut can be

influenced by the driving speed and number of shredding bars (depending on type). The more
shredding bars you use, the shorter the cut. But with more shredding bars you use more
power and lower the capacity. The slower you drive, the longer the mulch spends in the
housing and the more it is chopped.
Recommendation: Generally speaking, only use one shredding bar. Müthing mulchers are so
constructed that a single shredding bar will produce an adequate quality of mulch. Only use a
second shredding bar (can be fitted later on larger machines) for special circumstances (e.g.
for sensitive grazers such as horses and when you want rotting to take place as quickly as
possible).

 Conscientious maintenance.
 Too little grease means that the bearings will not be lubricated, will run hot, jam and may

even be destroyed. If you carry on driving the journal bearings will break. Grease often and
protect your machine!

 Too much grease will push the entire bearing apart, and dirt will penetrate and eat into the

bearings. Don't use too much grease or too high a pressure when lubricating!

 Check oil levels before using the machine for the first time and then check them as

described in the maintenance schedule.

 Drive belts are not made of steel. They get longer the first time they are used. It is essential

to retension the drive belts after a short time (no longer than 30 minutes)! Then check the
tension from time to time and retense them if necessary.

 Screws settle after being used for the first time. Check nuts and bolts conscientiously!

You will find further information in the following maintenance schedule.

9) Cleaning and servicing the machine after it has been used for the first time enables you you

to carry out a good visual inspection and helps to maintain the value of your Müthing –
mulcher. Use grease to expel any water that has got into the bearings.
Check flails and mountings! Change worn parts immediately instead of waiting until the next
time you use the machine.

10) Damage. If the mulcher is damaged you must stop work immediately. Damage to safety-

related components endangers your life and limb. Damage to rotating parts will get worse
if you carry on driving. Damaged or lost tools (scoop flails or tungsten carbide hammer flails)
cause imbalance, which can destroy the entire machine.

You will find detailed instructions on operating and maintaining equipment under points 7,
8, and 9 of this manual.

6. Safety

The following words and symbols are often used in the Instruction Manual for particularly important
information:

• Note:

Special information, instructions and regulations for avoiding injuries to

people, damage to property and avoiding accidents.

If you see this symbol please be aware that there is a possibility of personal injury or
damage to property.
Please read the following information closely and pass it on to anyone else using the
equipment.

• Note: Special details concerning the efficient and economical use of the machine and
features requiring particular attention .

Note: Always adhere to the Safety and Accident Prevention

Regulations listed below !

Appropriate use

Your Müthing mulcher uses up-to-date technology and has been built to comply with all the latest
safety regulations. Despite this, the mulcher can still present a danger to life and limb of the user
and third parties, and damage can be caused to property, the tractor and the mulcher itself if it is
used for unsuitable purposes or otherwise misused.

The mulcher can only function safely, efficiently and without any technical problems if the Instruction
Manual is closely adhered to.

Note:

Any faults that can affect the safety and operation of the mulcher must be

rectified promptly by a trained mechanic.

The mulcher has been design specifically for grass and similar light undergrowth, such as the
trimming of plant stems to within a finger width from the ground.

The mulcher is only suitable for mulching flat areas and for ditches, slopes, path edges and dikes
etc. in farming, landscape gardening or communal areas. Generally speaking a Mulcher can only be
used at the absolute minimum distance when the whole mulcher casing is parallel with the ground.
There are no other acceptable uses for a mulcher. If it is used for any other application the user is

solely responsible for any damage that may result.

Appropriate use also includes adhering closely to the manufacturer's guidelines on operation,
maintenance and repair, complying with regulations relating to inspection and servicing schedules
and maintenance and adhering to safety instructions and notes on risks plus accident
prevention regulations.

The mulcher may only be serviced or repaired by someone who has an in-depth knowledge of its
technical characteristics and is familiar with necessary safety precautions.

It is advisable to practise the separate working stages several times, so that you are familiar with the
effect that the mulcher has on the tractor, before carefully beginning the first jobs.

Instruction manual – MU-C/S 17

Note:

All accident prevention, health and safety, traffic and other generally

recognised regulations relating to safety and occupational medicine must be
complied with at all times to constitute appropriate use.

Your mulcher is a piece of equipment that requires proper handling. The mulcher must never be
used by children, teenagers or other people who are not familiar with the Instruction Manual

.

Note:

Carrying passengers on the mulcher whether you are working or not is

prohibited. It is also prohibited for people to stand on or climb on to the
machine or position themselves underneath the machine without adequate
support and safeguards even when it is stationary

!

People are prohibited from loitering in the mulcher danger area when the

machine is being started or used. The safe distance for people to stand behind
the mulcher is 80 m and must be adhered to.

Don’t use the mulcher at night or in poor visibility.

Leave the machine in the condition it was built for – to be used as a mulcher. You must not make
any additions, alterations or modifications to the mulcher without consulting us and obtaining our
written permission beforehand. This also applies to installing or changing the settings of safety
devices.

Note: Existing safety devices must not be altered or removed. Do not make any

changes or modifications!

Changes and alterations will invalidate the warranty and may give rise to legal action if the user
injures a third party or causes damage to property.

Note:

Please note the maximum tractor power allowed for the mulcher. The use of a

more powerful tractor can damage the mulcher and such damage is not
covered by the warranty.

Before using the tractor/vehicle and mulcher familiarise yourself with their

characteristics and be sure to read the manuals for the tractor, the mulcher
and the P.T.O. drive as well as this Instruction Manual.

Note:

Only fit original Müthing replacement parts.

These ensure a perfectly fitting, quality component and preserve your

warranty.

Improper use

The mulcher may only be used as described above. Any other use than that described above is
improper and consequently impermissible. It will invalidate all warranties, guarantees and
product liability entitlements!

Improper use includes:

• using the mulcher to break up or loosen the ground or carrying out any other work on the soil or its
surface
